DRAFT-EQUALIZER.

Specification of Letters Fatent.,

Patented Feb. 11, 1908.

Application led January 26.1907. Serial No. 354.324.

To all whom it may concern:

Be it known that I, LEO W. RAUCH, a citizen of the United States, residing at Avon, in the county of Bonhomme and State of South Dakota, have invented a new and useful Equalizer; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a draft equalizer, said invention has for its object, essentially, to provide a simple and efficient device which will equalize the draft of the animals at all points, asis evident from the hereinafter description in connection with the accompanying drawings; this device is very effective in its construction and operation, strong and durable, easily and readily adjusted, and at the same time comparatively inexpensive in the cost of manufacture.

The device comprises a main equalizing bar, a supplemental equalizing bar, pivoted to the main equalizing bar, a doubletree and a plurality of swingletrees, all of which are hereinafter described, and shown in the accompanying drawings.

This invention comprises further objects and combinations of elements which will be hereinafter more fully described, shown in the accompanying drawings, and the novel features thereof will be pointed out by the appended claims.

To obtain a full and correct understanding of the details of construction, combinations of features, elements and advantages, reference is to be had to the hereinafter set forth description and the accompanying drawings in connection therewith, wherein Figure 1 is a top plan view illustrating the said invention. Fig. 2 is a perspective view of the main equalizing bar, showing the peculiar construction of the connection of an angle bar, in connection with the said sup lemental bar and a second supplemental ar. Fig. 3 is a sectional view on line 3-3 of Fig. 1. Fig. 4 is a plan view of the equalizer showing the parts in different positions. Fig. 5 is a detail view of the main equalizer bar, showing the seat for the pivoted angle bar.

Making renewed reference to the accompanying drawings, wherein similar reference characters indicate corresponding parts in the several illustrations, by figures, 1 designates the main equ alizing bar having pivoted thereto a supplemental equalizing bar 2, by means of a clevis 3; this clevis 3 is fixed in a recessed portion 4 of the end of the main equalizing bar, as clearly shown, that is, the lower arm thereof. One end of the main equalizing bar, as at 5, is provided with a connecting clevis 6, which clevis 6 is pivoted to a plate 7, carried by the doubletree 8, which at each end thereof, is provided with a clevis 9, which clevises pivotally carry the swingletrees 10, which are designed for a pair of horses.

The supplemental equalizing bar, at one end thereof, is provided with a clevis 11,

' which carries a swingletree 12; the other end of the supplemental equalizing bar is provided with a clevis 13 which clevis is disposed upon an angle and is pivoted to a second sup plemental equalizing bar 14 of smaller proportions than the first-named supplemental equalizing bar; this equalizing bar 14, at one end thereof, as Yat 15, is provided with a clevis 16, to which a swingletree 17 is connected, as clearly shown. The other end of the equalizing bar 14, as at 18, is pivotally connected to a pivoted angle bar 19, which is pivotally connected to the main equalizing bar, as at 20; this angle bar is seated within a recess 21, of the said main equalizing bar,

as clearly shown. This angle bar is pivot ally connected to a clevis 22, which comprises a pair of arms 23 which straddle the main equalizing bar, as clearly shown; the pivotal pin 24, of the clevis 22 and the angle bar plays within a notch 25 of the main equalizing bar, when the parts of the device assume the positions as illustrated in Fig. 1 of the accompanying drawings. This clevis 22 is designed to be connected to the object to be drawn, as will be clearly evident from the drawings. This equalizer is designed to be used in connection with most any construction of vehicle, that is, any vehicle for hauling heavy loads, but is more eifectually hadapted for use in connection with plows or other agricultural implements.

It is to be understood that various changes and modifications may be employed in the construction and embodiment thereof, com- -binations of features, and elements, without in any way departing from the spirit and scope of the invention covered by the claims thereof; it being understood that whatever variations or modifications are employed must fall within the scope of the appended claims.

From the foregoing, the essential features,

elements and the operation of the device, together with the simplicity thereof, will be clearly apparent, and, when manufactured in accordance with the invention, a market will be easily obtained therefor.

Having thus fully described the invention, what is claimed as new and useful by the protection of Letters Patent, is

A draft equalizer, comprising a main equalizer bar, a supplemental equalizer bar pivoted intermediate its ends,vin one end of the main equalizer bar, a second supplemental equalizer bar, a clevis pivotally connected to the inner end of the first-named supplemental equalizer bar and to the second-named equalizer bar, intermediate the ends of the latter, the said main equalizer bar having an elongated recess, said recess having a projecting flange, two angled members forming a clevis pivoted to the inner end of the second main supplemental equalizer bar and to the fiange of the said recess, said angled members being received by the said recess and a clevis pivoted to said members and adapted to be attached to the object to be drawn, a notch formed between the end of said 'flange and the end of the said recess to receive the pivot of the said angled members and the clevis, and draft means attached to the free ends of the equalizer bars, substantially as described and for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

LEO W. RAUCH.
